Florfenicol is a commonly used veterinary antibiotic with broad antibacterial spectrum, strong bacteriostatic effect, low minimum inhibitory concentration (MIC), and its antibacterial effect is 15-20 times that of chloramphenicol and thiamphenicol. 60 minutes after administration, the drug concentration in the tissue can reach the peak value, which can quickly control the disease. It has the characteristics of high safety, non-toxicity, and no residue. There is no potential hidden danger of aplastic anemia. It is suitable for large-scale large-scale farms. For the treatment of bovine respiratory diseases caused by Pasteurella and Haemophilus. It has good curative effect on bovine foot rot caused by Fusobacterium. It is also used for swine and chicken infectious diseases and fish bacterial diseases caused by sensitive bacteria. Florfenicol is not easy to develop drug resistance: because the hydroxyl group in the molecular structure of thiamphenicol is replaced by fluorine atoms, the problem of drug resistance to chloramphenicol and thiamphenicol is effectively solved. Strains resistant to thiamphenicol, chloramphenicol, amoxicillin and quinolones are still sensitive to this product. Because chloramphenicol has serious adverse reactions such as aplastic anemia and immunosuppression, its use in food animal production is prohibited. Studies have shown that the main group in the chemical structure of chloramphenicol that causes aplastic anemia is the para-nitro group on the aromatic ring. While florfenicol replaces the NO2 group with CH3SO4, the chemical structure has changed, so it does not produce adverse reactions of aplastic anemia in animals. Therefore, it is approved for use in more than ten countries in Japan, Mexico and China. The characteristics of florfenicol are: broad antibacterial spectrum, against Salmonella, Escherichia coli, Proteus, Haemophilus, Actinobacillus pleuropneumoniae, Mycoplasma hyopneumoniae, Streptococcus suis, Pasteurella suis, B. bronchiseptica , Staphylococcus aureus, etc. are all sensitive. The drug is easy to be absorbed, widely distributed in the body, is a quick-acting and long-acting preparation, has no hidden danger of potentially causing aplastic anemia, and has good safety. In addition, the price is moderate, which is cheaper than other drugs for the prevention and treatment of respiratory diseases such as tiamulin (Mycoplasma), tilmicosin, azithromycin, etc., and the cost of medication is easy to be accepted by users. Due to these characteristics, domestic florfenicol has been widely used, and it has become the drug of choice for the prevention and treatment of bacterial infections of the respiratory tract and digestive tract of livestock and poultry. Florfenicol should not be used in combination with quinolones, penicillins, and cephalosporins, and should not be combined with ampicillin, sulfonamides, and furans.
